User:Vanessa R Garcia/Gene redundancy


 * my changes in bold

Gene redundancy is the existence of multiple genes in the genome of an organism that perform the same function. '''Gene redundancy is the result of gene duplication. Such duplication events are responsible for many sets of paralogous genes (is this addressed in the first source?) .''' When an individual gene in such a set is disrupted by mutation or targeted knockout, there can be little effect on phenotype as a result of gene redundancy, whereas the effect is large for the knockout of a gene with only one copy.
